Carmel-based Zeke Turner is chairman and CEO of HealthLease, which is listed on the Toronto Stock Exchange. He’s also founder and CEO of Mainstreet Property Group, a Carmel firm that specializes in building nursing and retirement homes.

Turner’s father is state Rep. Eric Turner, R-Cicero, who also has a financial interest in Mainstreet Property Group. Eric Turner has been under scrutiny recently for helping kill legislation that would have hurt the family’s business.

Mainstreet formed the HealthLease Properties in 2012 with an initial portfolio of $100 million, an 850 percent increase on investment in just two years, the company said.

In the deal announced Wednesday, the Toledo firm also purchased 17 still-being-built properties from Mainstreet’s Next Generation wing, which operates nursing homes specializing in short-stay acute care for seniors after medical procedures.

The two firms also announced a development partnership of 45 future nursing homes across the U.S. and Canada. The combined value on those two deals was estimated at $1.4 billion.

Mainstreet officials said in a statement the deal would create “the leading short-stay rehabilitation and therapy development partnership in the United States.”

Company spokeswoman Kit Werbe said Zeke Turner out of town the rest of the week and unavailable for an interview, but in a statement, Turner said he was “grateful and humbled to team up with such a great partner” and that “Americans deserve better choices for their health care and this partnership is built to offer just that.”

Mainstreet said it expects the deal would generate thousands of new jobs across the country, including 20 new jobs at its Carmel headquarters.

The deal is expected to close in the fourth quarter of 2014.

The sale comes four months after the House ethics committee ruled the elder Turner did not violate the chamber’s ethics rules.

Eric Turner, the powerful speaker pro tempore in the Indiana House, worked behind the scenes in private caucus meetings in the last legislative session to kill a ban on new nursing home construction in Indiana.

The ethics committee found that Turner had not acted in the “highest spirit of transparency,” but he technically broke no rules, which only prevent lawmakers from voting on issues in which they have a financial interest, not from advocating on them.
